What does the Bible say about being ready for the Lord's return?

The Bible, particularly in Matthew 25:1-13, illustrates the necessity of being ready for the Lord's return through the parable of the ten virgins. In this parable, the wise virgins prepared properly by bringing oil for their lamps, symbolizing the need for true faith in Christ. The foolish virgins, lacking oil, represent those who may outwardly appear part of the faith but do not possess genuine belief. The key takeaway is that each believer must personally ensure they are ready, as the timing of Christ's return is uncertain, whether it be through death or His second coming. This parable encourages believers to cultivate an authentic faith, rooted in an inward work of grace bestowed by the Holy Spirit.
